Description
Technical field
This utility model is related to a kind of applanation bearing, and more particularly, to one kind automotive suspension amortisseur is mainly used in
On, the applanation bearing of the high stability of bearing automobile car body weight and car assisted steering.
Background technology
Bearing is, for determining rotary shaft and other parts relative motion position, to play the parts of supporting or guide effect.
It is that part that is fixed and reducing load coefficient of friction is played in mechanical transmission course.It may also be said that when other parts are on axle
Each other produce relative motion when, for reducing power transmission process in coefficient of friction and holding shaft center fix machine
Part.
Plane bearing is primarily subjected to axial load in assembly, and it is widely used.Existing applanation bearing arrangement
Simply, therefore plane bearing installation operation is also fairly simple, but still often an error has occurred during actual maintenance, i.e., the tight ring of bearing and
DNA releaxed circular DNA installation site is incorrect, as a result makes bearing ineffective, and axle journal is soon worn.
If tight ring inner ring and axle journal are interference fits, tight ring is driven when axle is rotated, and is rubbed with static element end face,
When by axial force, moment of friction is will appear from more than the minor diameter fit moment of resistance, cause tight ring to force to turn with axle mating surface
It is dynamic, aggravate journal wear.
For the problems referred to above, a kind of applanation bearing is now designed, realization is easily installed in place on bearing, the bearing after installation
It is stable, not easy to wear.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of applanation bearing of high stability, overall structure
It is stable, in motor process, it is less prone to the failures such as damaged and steering abnormal sound.
This utility model solve the technical scheme that adopted of above-mentioned technical problem for：The applanation bearing of high stability,
Including lower cover, upper lid and circle is kept, described upper lid and the rotatable clamping of lower cover, described upper base portion is provided with annular the
One groove, is provided with annular second groove at the top of described lower cover, the first track is provided with the first described groove, described
The first track bottom surface be provided with arcuate structure first depression, the second track is installed in the second described groove, it is described
The top surface of the second track be provided with the second depression of arcuate structure, described holding circle is arranged on the first track and the second track
Between, described holding circle is circular ring structure, is evenly distributed with multiple steel balls on described holding circle, described the first track,
Second track, the cross section for keeping circle installation composition rectangular configuration.
The further preferred version of this utility model：The bottom surface of the first described groove outer wall is provided with the of fold inward
One flanging, the top surface of the second described groove outer wall is provided with outwards the second flanging of turnover, the inwall top of described the second groove
Face is provided with the 3rd groove snapped in for the first groove inner wall, and the outer wall of the second groove is stuck on the outer wall of the first groove.Upper lid
Structure setting between lower cover, it is ensured that it is stable above to cover with being connected between lower cover, it is not easy to shifted, causes aggravation
Journal wear.
The further preferred version of this utility model：The diameter of described steel ball is less than between holding circle external diameter and internal diameter
Difference.The diameter of steel ball is less, by the first track, the second track clamping its entirety can be made to become stable square-section knot
Structure.
Compared with prior art, the utility model has the advantage of keeping circle to be circular ring structure, keep being uniformly distributed on circle
There are multiple steel balls, the first track, the second track, holding circle install the cross section for constituting rectangular configuration, can be good at keeping
Circle is limited in pre-position, it is not easy to which shift problem.The design keeps the position of circle, and overall presentation one by limiting
More stable rectangular cross section structure.The first track, the second track, holding circle are arranged between upper lid, lower cover again.It is upper lid with
Lower cover constitutes together a cavity for keeping circle motion.
Description of the drawings
Fig. 1 is decomposing schematic representation of the present utility model；
Fig. 2 is partial sectional view of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings, this utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only to explain this
Utility model, is not used to limit this utility model.
As shown in Figure 1 to Figure 2：The applanation bearing of high stability, including lower cover 2, upper lid 1 and holding circle 3, upper lid 1
With the rotatable clamping of lower cover 2, the bottom of upper lid 1 is provided with annular first groove 4, and it is recessed that the top of lower cover 2 is provided with annular second
Groove 5, is provided with the first track 7 in the first groove 4, the bottom surface of the first track 7 is provided with the first depression 9 of arcuate structure, and second
Second track 8 is installed, the top surface of the second track 8 is provided with the second depression 10 of arcuate structure, keeps circle 3 to install in groove 5
Between the first track 7 and the second track 8, keep circle 3 to be circular ring structure, keep being evenly distributed with multiple steel balls 11 on circle 3, the
One track 7, the second track 8, the cross section for keeping the installation composition rectangular configuration of circle 3.
The bottom surface of the outer wall of the first groove 4 is provided with the first flanging 21 of fold inward, and the top surface of the outer wall of the second groove 5 is arranged
There is the second flanging 22 of turned-out folding, the inwall top surface of the second groove 5 is provided with the 3rd groove 6 snapped in for the inwall of the first groove 4,
The outer wall of the second groove 5 is stuck on the outer wall of the first groove 4.
